System composition and measurement principle:

The system consists of a launch vehicle, a measurement vehicle, and a feedback vehicle. The launch vehicle and feedback vehicle are fixed at both ends of the road section to be tested. The launch vehicle emits two collimated laser beams horizontally and vertically and aligns with the feedback vehicle to form a reference; The measuring vehicle is pushed on the road section to be measured, and the displacement of the collimated laser beam is measured by high-precision CCD and converted into various geometric parameters. The feedback vehicle monitors the real-time jitter of the collimated laser and promptly transmits the jitter amount to the measurement vehicle for correction, eliminating the impact of laser jitter on the measurement results.

Measurement principle and purpose:

DK type track levelerIt is a high-precision instrument that uses the principle of photoelectric imaging for precise measurement of various geometric parameters of the track. This instrument integrates optics, mechanics, electronics, and wireless networks, and uses a special light source and CCD image sensor to perform high-precision detection of railway track geometry, enabling direct digital display of parameters such as track height and orientation. Providing reliable measurement data for the maintenance of line equipment, solving the problems of poor measurement accuracy and low efficiency of existing methods, meeting the requirements of "skylight repair" night work in engineering and improving the quality of night work.

This instrument can measure high-low and orbital parameters within a 200M long wave range. Providing reliable and effective data for precise adjustment and maintenance of the line is a powerful supplement to the absolute measurement of high-speed rail CPIII.

1. Routine geometric parameter testing and construction operation guidance for railway engineering departments.

2. Re examination of the maintenance results of the track after major repairs.

3. Search for defects after the track inspection car alarms.

4. High precision measurement of track lines on high-speed passenger dedicated lines.
